graphic or planographic printing surfaces referred to in thisspecification are of the respectively well known kinds, theirconstruction being no part of the present invention.

The accompanying drawings illustrate a preferred constructional form ofthe improved press. In them Figures 1 and 1* together form a sideelevation showing all the organs necessary to the thirteen capacitiesenumerated above. Fig. 2 is a side elevation of the sheet-grippertumbler; Fig. 3, a side elevation of a winch handle-for turning theadjusting eccentrics of a certain cylinder; Fig. 4, a'sectional detailof a gripper opener; Fig. 5, a sectional detail of a. substitute gripperopener; and Fig. 6 a sectional detail of the connection between acertain gear wheel and the shaft of the Hat bed motion. Q j

I will describe first, the organs of the improved press and their mutualrelationship;

secondly, the means by which it is adapted foreach of the thirteen presscapacities; and then proceed to'define by the claims, the severalfeatures of the invention.

1. The organs and their mutual relationship.

1 is one of the side frames; 2, the first motion shaft; 3, a gear faston it and meshing withthe gear 17; 4, a gear fast on the shaft 2 andmeshing with a second gear 5 axially fast to a gear 6 meshing with agear 7 fast on shaft 8; 11, a gear fast on the shaft 10 to meshalternately in the well known manner with the top and bottom racks 12'and 13, of the fiat bed 14; 15, the usual bedreverser engaging asheretofore in a yoke 16 at each end of the rack frame; 17, a gearnormally loose on the shaft 10 between an end plate 18 and a disk 19fast on the said shaft; and 20, 20 detachable bolts normally holding thegear 17 to the shaft 10 by being passed through both gear and disk 19.

= 23, the usual. mechanism for damping it when it is a planographicsurface. When it is a typographic one, the damping mech'as nism 23"ispnt ontof action b the removal of its rollers. The inking sla (not shownfor want of space) occu les the'usi'ial 'pos'ition at the right-handlooking at Fig. 1' of the bed 14.

24, is a cylinder driven by the gear 17 through a gear 25 axially fastto the former. 26 isa second cylinder and 27, athird-one. The twocylinders 26, 27 ,have ractically a common diameter which is half thatof the cylinder 2.4;and a common rate of rotation conslderedperipherally. 'These three cylinders are geared together, the cylinder24 bi ng. driven by the gear ,17 or by another 0 the same size. When thesaid gear 17 is loose on the shaft 10, it, b reason of its meshingwith'the gear com ined with the pulley 3, serves as an intermediate gearto transmit the driving effort from .the shaft 2 to the said threecylinders.

,2 8 is one of the bearings of the cylinder 24 both bearings '-having arise and drop in the side frames 1' to provide for the said cylinderbeing tripped and untripped with respect .to the-printingsurface 21.

29, 29 are springs resilient between a ledge 30 on the'respective sideframe 1 and the bottom face of the respective bearing. 28, and:therefore, when they'are free to do so automatically holding thecylinder 24 tripped i. e., out printing coiipeiati'on with the form21.

31 is a block fast to the bottom ends of two rods 32 fast by their topends to the respective bearing 28.

33 is a cam groove axially fast to the gear 7 and embracin and rockingthe projecting end of the pin" 4", it'hich pivotally connects ahook 35to the outer end of an arm 36 mounted on a suitably supported shaft 37.The weight of the hook 35 tends to keep it in engagement with a secondarm 38 likewise fastron the shaft .37 and having incorporated with it,an eccentric 39 capable of depressing the block 31 to-untri the cylinder24, i. 0., to put it in print n co6peration' with the surface 21, and ofisengaging from the said block to allow the springs 29 to trip the saidcylinder. .The hook 335 and its cooperating organs constitutes; wellknown combination.

40 is a foot pedal-standing up above the feeders foot-board 41, its red42 pivotally connected to one end of a lever 43 fulcrumed on a sideframe 1 at 44 and. having a cam shaped ledge 45 at its opposite endadapted to engage, when the pedal 40 is depressed, with a roller 46 onthe book 35 to disengage the latter from the arm 38' and to hold itdisengaged therefrom as long as the cylmder .24 is to remain tripped.

nect-the cylinder 24 i'r'oni the eccentric 39.

'48 is"): set 'scre'w'worlting upward through each s1de frame 1 againstthe bottom face of the respective block 28 to hold the cylinder24tripped, It is not considered that the combination of he above describedorgans28 to 48 inclusive is new.

The cylinder 24' has two operative surfaces, 49 and 50, each of which isan imptession surface or-a'n offset surface accordm'g-to the[presscapacity called for.

'51,. 51,: are the two reel rods for the blanket to make the surface 49an ofi'set one; and: 52, 52, are the like {for the blanket to makethesuriace 5.0 an ofiset one. The paper to he printed is fed. in sheetform orig: v

53 is e feed board; 54, the sheet guide; 55, the gripper for the surface49; 5.6-, that for the surface w; 57,.the stripper; and. 58, thedelivery tapes.

- 59 is the tumbler for operating the grippeis; 60, its closing pin; 61,its opening ping. .62, ,theigripper pm lever; and 63, the cam axiallyfast to the shaft of the cylinder 24; for operating that lever.

-'s the'lower-blade of the lever 6,2; 65, 4) asubstitute lower blade;and 66, a substitute. opening pin, both to be substitutedfor the organs64 and 61 respectively for the. urpose of making the closing'pin60-.and! the opening pin 61 act together.

665, isa set screw to provide for a change in the angular position ofthe cam 63.

Turning. now ,to. the cylinder 26, it is held in rigid. connectionwiththe cylinder 24 so as to riseand dro. with it, by its bearing boxes 67capable o a vertical motion in the side'- fiianies 1,. by reason oftheir being operatively fast onbrackets 68. fast to to adjacent rodsThese brackets are verticallyf adjustable u on the said rods by nutsbelow them, toadjust the cylinder 26 in printin contact with thecylinder 24. .The cylin, er 2.6 has only one operative Surface, which isan offset one 72; and '73, 73, are the usual reel rods for therespective blanket. It coiiperates only with the cylinder 24 and istripped and untripped with respect thereto, from the gear 7 throughanequal gear 74 with which it enoove- 75 axiallyfast to the racing aroller 76 on an arm 77 rocking on a bracket 78 on one of the sideframes; a trip hook 79 engaging a stud 80 on the top end of the arm .77;a bell crank lever 81 fulcrumed on a bracket 82 fast. on the rods 32 andhavmg one arm pivotall connected to thev ad acent end of the trip' ook79 and the other to the bottom end of yahlch 18 can:

gear 74 and em nected to the arm 84 of the eccentric bearings of thesaid cylinder 26. There is a connection between the trip hook 79 and thepedal 40 by which the depression of the latter can trip both cylinders24 and 26. It consists of an arm 85 fast on a shaft 14, a link 86 fromit to an arm 87 fast on a stud 88 turning in the adjacent side frame andcarrying a cam 89 which will, by the engagement of a roller 90 on thehook 79 with it the next time the arm 77 is rocked to the left,disengage the said hook from the last men tioned arm whenthe cylinder26' is tripped. Means are provided for rendering the tripping anduntripping mechanism just de scribed, inoperative. These consist ofrocking the trip hook 7 9 upward by hand clear of both the arm 77 andthe cam 89 and resting it on a fixed stud 91, and further, of aneccentric 92 turning in each bracket 68 and in operative contact withthe respective box 07, both eccentrics to be turned together by a winchhandle 93 in the right direction to put and hold the cylinder 26 out ofcontact with the cylinder 24.

Turning now to the cylinder 27, it has only one operative surface whichis pianographic or typographic according to the press capacity calledfor. inking mechanism. The cylinder is shown as dressed with aplanographic sheet 95 held to it by clamping screws 96. 97 is the usualdamping mechanism to cooperate with the said surface when it isplanographic. It isput out of action by removing its rollers. Thecylinder 27 cooperates only with the cylinder 24 and is tripped anduntripped with reference to it by a cam groove 98 axially fast to thegear 74 already described, and embracing and rocking the projecting endof the pin 99 which pivotally connects a hook 100 to the outer end of anarm 101 mounted on a shaft 102. The weight of the hook 100 tends to keepit in engagement With one arm 103 of a bell crank lever' likewisemounted on the shaft 102 and having its opposite arm 104. pivotallyconnected to the bottom end of a connecting rod 105 the top end of whichis pivotally connected to the outer end of an arm 106 of the eccentricbearing 107 of the said cylinder 27. The tripping effect of a depressionof the pedal 40 described with reference to the cylinder 21, is broughtto bear upon cylinder 27, and in a substantially similar way, by an arm108 fast on the previously mentioned stud 88 and having acam shapedledge 109 adapted to engage, when the pedal 40 is depressed, with aroller 110 on the hook 100 to disengage the latter from the-arm 103.

111 is a set screw working downward through the hook 100 between itspivot and its operative end and bearing against a face on the arm 101 sothat screwing the screw 111 down through the said hook shall, by

printing 94 is the usual rocking it away from the arm 101, disconnectthe cylinder 27 from the cam groove 99 The whole of the mechanismappertaining to the cylinder 27' may be rendered inoperative. For thispurpose the pivot pin 112 connecting the rod 105 to the arm 106 isremovable. The cylinder itself is mounted in a frame 113 supported onthe rollers 11% of a track 115 on the frame 1 and the cylinder frame 113is held to the frame 1 by locking bolts 116 passed through lugs 117 onthe latter and lugs 118 on the frame 113, which bolts are alsoremovable.

11!), 119, are set screws working in the direction of the motion of theframe 113 along the track 115 through lugs 120 against opposite sides ofthe lugs 117 for the purpose of accurately adjusting the touch of thecylinder 27 upon the cylinder 24, and these lugs 120 are pivoted uponthe lugs 118 so that they can be rocked up to clear the lugs 117 whenthe frame 113 isto be moved back along the track 115 to render the saidmechanism inoperativesa-y as far as position 121or returned therefrom;122, indicates the inoperative position of the disconnected rod 105.Although the cam groove 98 is necessarily axially fast to the gear 74when they are working, it is adjustable about their common axis upon thesaid gear by bolts 123.
